How do I disable Chrome?

I have the Chrome browser on Android Lollipop. When a tab is closed, a bubble notification appears that says the tab has been closed, and offers to undo the action. How does one disable this? If I close 100 tabs a day, I see this aggrivating bubble 100 times a day. I might accidently close a tab once a month, in which case Recent in History will get it back in three taps. Do the math, Google.

Welcome to Android Central! I don't get that notification, because I have "Merge tabs and apps" turned off. This way, when I tap the tab manager icon in Chrome, I get the card view of all open tabs, and I can just swipe away tabs to close them. If you have "Merge tabs and apps" turned on, try turning it off.
